' n objetoffthe inventionis to;y provide a chimneyo this character provided with means for insulating the heat' Within the chimney so as, to eliminate the possibility oi? lire inthe building due to the yradiation of:I heat from the chimney. V

Another object of' the invention is to provide a. chimney of this character composed of a plurality of sections arrangedptojtelescopically, enoage v each other.V v

A. further. object of the invention is to provide a chimney Vof*` thist character compp 'sedolt a plurality ofsections, eachsection nolidillg. -Il inllo and outer Wall, With heat in siilatingnnaterial disposed' between saldi Walls, thoj'oild portions of" oaoll Sooton being adaptedlto telescope the end portions of the adjacent sections.A l

The section f'consists of; anouter tubular WallS constructed O metal, thewall tapering,- irom itsl end: 9A to its.- end 1Q, saidv end 10 4having `an inwardly projecting-*flange 1,1 adapted to reinforcesaid member'.

The end 9 is1adaptedto be imbedded-in a concretew base A. Itl is.:V of courseE obviousthat the; section 5 may ber made any length desired.' In onderIv toinsulatethe heat from the portionsv oft*thebuildings-adjacent the Wall 8, an inner Wall 12 is `pr0vided,.said Wall being tubularand tapering fromits endV portion 13 toits end;y portion 14,'the

-end portion 13 being embedded in theconportionsalOl and 14 ofthewallsfS-fandll isY V aI partition l'iwhich serves, to hold the :walls 8 and 12 in spaced relation to .eachother and to` coact with said-el Wallstoiprovide a, compartment 1-6 adaptedftoL receive; powdered asbestos, the'v asbestos serving toA insu-latethe ieat Within the tubular member 112; The portions of: the endpontionsll. andV 10 ofthe Walls 8 and: 12projecting beyond thev par- Y tition 15 are used as connecting meansv for connecting the lower end'. section-to the adjacent inter-mediate section.l To. facilitate cleaning, the endt section. is providedwith a soot pan 17 which ymay be readily removed.

In the constructionfof theV chimney any number ofintermediate sections may-be provided, t-he intermediatey sections Comprising an outer tubular metal Wall' 18` havingv laf iiange formedeXteriorly' of; the` eind portion 19 ofthe ivalflrand a', flange formed in- 'teriorly of the end lportion 2050il the Wall.

Disposed inwardly' off' the ivall 18 is an inner metallic tubular Wall- 21, the end portion 22 olf-'said' wall having a flangedisposed exteriorly thereof, While the end portion Q'Slrasa angefdisposed interiorly thereof; "A partitiein'24 is disposed inwardly of the end portions 2O and 23and^1-9 andv Q2,

fsa-id' partitions` coacting'with the Walls-18 and: tp provider;v compartment 24st adapta ed, to receive poyvdered asbestosso as tol loofV insulate the heat within the tubular wall 21. The intermediate section that is adapted for engagement with the end section is provided with registering openings 25 inthe walls 21 and 18 through which a flue 26 extends, said flue extending through the compartment 241;a and is Vadapted to receive the end of a pipe leading from the heating plant. The end portion 19 of the tubular wall 18 has a collar 27 secured thereto, said collar terminating at the lower partition 2d and is also disposed between the walls 18 and 21. Ak similar collar 28 is secured to the inner face of the tubular wall 21. The collar 28 coacts with Athe end portion 22 to provide a compartment for the reception of the endportion 11i of the section 5, while the collar '27 coacts with the end portion 19 to provide a collar for the reception of the end portion 10 of the section 5. In this way a pipe joint Vis provided which not only prevents 'leakage of smoke and gases, but at the same time the heat is prevented from reaching the outer tubular walls of the sections. It will also be noted that in the engagement of the sections 7 with the sections 5 that the flanges onthe ends of said sections are so disposed that they donot conflict or interfere with each other and at the same time properly reinforce the ends of the sections. Any number of the sections 7 may be provided, and it is not necessary that collars 27 and 28 'be provided for each of theintermediate sections, but only the section adjacent the end section 5.

The top or chimney shaft section, similar to the sections 5 and 7, comprises an outer tubular wall 29 and an inner tubular wall 30 which are spaced from each other, the end portion 31 of the wall 29 having a flange disposed exteriorly thereof, while the end portion 32 of the wall 80 has a flange disposed eXteriorly thereof and between the walls 29 and 30. A partition 33 is disposed between the Walls 29 and 30 while a top member 84 is secured to the upper ends of the walls 29 and 30, the top Bet and partition 83 coacting with said walls to provide a compartment 35 for-the reception of powdered asbestos.

In this construction it is of course Yobvious that a chimney cap' 36 may be secured to the top 35 andv outer wall 29, and in the construction of this cap solder may be used as the asbestos prevents the radiation of heat and thus eliminates melting of any solder used in the formation of the cap. The end portion 31 of the section 6 is adapted to telescope the end portion 2O of the section 7 exteriorly of the end portion 20, while the end portion 32'of the section 6 is arranged to telescope the end portion 23 of the section 7 likewise exteriorly of said end portion. Telescoping movement of said ends is limited by contact of the flanges of said sections with the adjacent partitions between the walls. Y

In the construction of theA end section 5,

it is preferred that the inner and outer walls be constructed of galvanized iron, while the inner walls of the remaining section-are constructed of copper and the outer walls of galvanized iron, the copper serving to retain the heat within the chimney. j It will also be noted that the partitions of each end portion of the sections are disposed inwardlycof the sections a distance corresponding to the length of the end portions projecting beyond the partitions so that each partition serves asa stop for the telescoping ends ofthe adjacent section.

From the foregoing it will be readily seen i that this invention provides a novel form of chimney which is not only capable for use in small houses, but also in factories, as it can be made any size or length desired. The temperature of the heat within the chimney does not have to be watched or regulated, as there is no danger of fire in view of the protection afforded by the inner walls and the asbestos compartments.v asbestos within the compartments serves as means for holding the sections .in engagement with each other, in view of the weight thereof. All of these features are possessed by a chimney composed of sections capable of being readily assembled. n

What is claimed is o 1. A chimney comprising a plurality of sections, each section embodying an inner and outer tubular wall, spacing means disposed between said walls, said means coact- Furthermore, the

ing with the walls to provide a compartment v for the reception of heat insulating means, the end portions of said sections telescopically engaging the end portions ,of the adjacent sections.

2. A chimney comprising a plurality of sections, each section embodyingan outer tubular wall and an inner tubular wall, one end portion of each of the end sections and both end portions of the intermediate sec-` tions having partitions disposed inwardly thereof between theinner and outer walls,

said partitions coacting with the inner and outer walls to provide compartments for the reception of heat insulating means, that portion of the end portions of said sections projecting outwardly from thev partitions telescopically engaging the corresponding end portions of the adjacent sections, said partitions serving as meansjto limit telescopic movement of said sections.

. 3. A chimney comprising a pluralityV of sections, each fsection embodying an inner and outer Vtubular wall, partitions disposed` y inwardly of the end portions of said walls for spacing the inner and outer walls from each other, said partitionsl coacting' with said walls to provide compartments arranged to receive asbestos, that ,portion of the end portions of each section projecting beyond the partitions telescopically engaging the end portions of the corresponding tubular walls of the adjacent sections, the intermediate section of the chimney adjacent the lower end section having collars disposed insignature.

wardly of the lower end portions thereof, f

said collars coacting With the adjacent end 10"v Vportion of the intermediate' section for the `reception of the end portionsfof the lower end section.
